DMux4Way & 8Way

[utsav]

I built DMux4Way using 2 Not gates and 8 And gates.  I couldn't built it using DMux gate.
by this method DMux8Way will require 4 Not gates and 12 And gates. So? Could it be built in a better way or is this fine ?

It's OK to build the parts any way that works.  After completing the hardware chapters, some students review their designs and can improve them using what then have discovered along the way.

For the DMux4/8Way think about mirroring the Mux4/8Way. If you made the Mux4Way using cascaded Muxes, turn the design around swapping inputs for outputs.

Thank you so much for your help cadet1620.

Using your suggestion to "think about mirroring": I redid my Mux implementation based on my DMux implementation.

This also helped me finish my DMux4Way and DMux8way. I looked at Mux4Way16 and Mux8Way16 diagrams/drawings spun the paper clockwise and worked on the inputs and outputs.

Thank you!

Could you show me your demux4way.hdl
 I can't build it using and and not gate .  
I wonder how dose it work .  plz

We don't encourage just showing people the solutions. That really detracts from the learning opportunities that struggling with doing it yourself provides. It can be frustrating, but it is an excellent way to actually learn.

Your code in your other thread (which is the best place to continue the discussion) is on the right track. So I'll offer some suggestions to help you move forward over there.
